Hi Discorde: I was not trying to open a debate about damage/no damage descent techniques I was merely trying to draw attention to an area that in my experience is scantily covered during training. Namely the risk to passenger health at excessive cabin altitudes. Once below 30,000ft. the risk is vastly reduced. I am sure that you will remember that a certain three- engined product from Hatfield did not even have a pax dropdown system fitted! Cue here to review response time!
This factor is more common now with so many aircraft operating at F390/F410 today.
